Abstract
In order to identify the structure of the surface of AlN, an infrared study was conducted. AlN powder was thermally treated either under vac uum or under controlled atmospheres using probe molecules at different temperatures. The surface presented OH and NH groups originating from the hydrolysis of Al-N bonds as well as Al3+ Lewis-acid sites (Al3+ i ons in both tetrahedral and octahedral coordination). Some Al-H bonds were also present.
